One of the rarest of all flavors of the Mini Cooper S, a 970 S built in 1964 comes up for auction at the Silverstone Classic on 29th – 30th July. A fine example of the homologation special created to qualify the Cooper S for the under 1000cc category in racing and rallying, the car presented by Silverstone Auctions is one of less than a thousand ever built. With engine and chassis numbers matching logbook records and an extensive history file including homologation papers, heritage certificate, 2004 FIA Historic Technical Passport and MoT certificates, the iconic Cooper 970 S is estimated to sell for between £43,000 and £50,000.
